vespa piaggio malossi variated race GEARBOX




NEW malossi variated gearbox for vespa piaggio mopeds! completely brand new casting!

from malossi:

"We added ribs to strategic sections to increase stiffness. We increased the diameter of the wheel shaft bearing and of all the others, and added ribs to compensate the increased performance. All within the original space: the gearbox uses pressed needle bearings for all gearbox shafts, NBR oil seals with spring sealing lip and auxiliary lip and a labyrinth to trap the oil and at the same time allow the gearbox to " breathe".

The gearbox simplifies the gear housing, improves brake shoe operation with dedicated machined surfaces to guide it more accurately. Two concentric positioning bushes closed by five screws (one more than the original), with hexagonal cylindrical head. The gearbox uses high quality steel pins, pressed into the crankcase, for the lever and brake shoe pins. To improve rigidity, we have eliminated the gasket: everything is sealed with silicone paste as in the most modern vehicles ( Permatex Motoseal Ultimate Gasket Maker - Grey that you find in our catalogue is perfect).

The swingarm fixing screws are now pass-through and doubled in length, with a special sealant applied to the thread, as to guarantee top-level fixing. The gearbox is supplied complete with bearings, oil seals, screws and shims: everything needed for A perfect assembly with Malossi gears (but if you want you can also assemble it with the original gears). "
